IMPROVED METAL ROOFING.

'IO ALL WHOM IT MAY CONCERN:

Bc it known that I, JOHN B. STHYKER, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Mode of Putting onMetal Rooiing; and I do hereby declare the following to be afull, clear, and exact description of the nature thereof, which will enable others skilled in the art to which it appertains to fully understand and use the same, reference being had to the accompanying drawing, making partof lthis specification, and which represents a perspective view of a roof constructed according to my invention.

This invention consists in applyingl grooved strips directly to the roof, and on which the ends of metal sheets are secured, thev end of onebeing n ailed to the strip, the nails passing Lthrough which and into the roof,

and the end of the adjacent sheet overlapping andcovering the end of the nailed sheet,'and soldered thereto,.

whereby the ends of bothshects are secured to the same strip, thus admitting suiicient roo'm or play for the expansion and contraction of the metal without detriment thereto, as will be hereinafter more fully described.

In the drawing, A represents an ordinary wood roof, on the upper side of which I place at proper intervals strips B, extending from top.to bottomof t'he'roof. These strpsare of suitable form, but grooved on their upper sides for the distance of their lengths, as shown at A. a represents a sheet of metal, 'one end of which is secured on the under side of thereofA by beads; or other suitable means. b is the adjacent sheet, one end of which is passed over the strip Bj andis secured thereto by nails or equivalents, which pass through the strip into the roof, so that they accomplish two results, Viz,'securing the metal to the strips and the strips to the roof. l

The inner endof' sheet a is thenvpassed over the nailed end`ot` sheet b, and soldered thereto at the inner upper termination of the groove A', as shown at a. It will thus be seen thatthere is no exposure ot' the seam, and water will lowdown the groove without'any opportunity to passte the roof through the seam a', which, if not :entirely closed, would be the only communication with the roof. The next sheet, c, is then secured to the strip B the same as sheet b, 'and the inner end of sheet b is brought over to overlap the nailed endot` the sheet c, and then secured by soldering, as in the previous case. The remaining sheets of metal1 are applied in the same manner as the other ones, and the side and end of the last sheet' are secured by mouldings or other suitable means to the under side-of the roofl When the roof is liable to be affected by thc wind, I employ an voval strip, B', which is encased or covered by metal, and the sheet passed over the same. The strip will be nailed to the roof, and the sheet be soldered to the metal on the strip. l l

As I employ a meta'hwhich is self-soldering, it will only benecessary to apply the soldering-iron on the metal, and it will immediately solder with the sheetin' contact with it. It will also be seen that the'metal is of so ductile a nature that the strips-will be readily lapped by merely pressing the metal over the strips with any suitable tool A metal root` constructed according to my invention, will allow of free expansion and contraction of the metal, whether caused by heat or cold, or the cracking or warping of the wood underneath. No seams are exposed to the wind or water, and, as the lnails or screws are concealed, there is no possibility ofthe metal being torn by the-force of the wind.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A roof composed of transverse sheets a b c, one side ofc-ach oi' which is passed over ,and nailed to grooved strips B, and thcother side soldered to the adjacent sheet over the strip, and covcring the edge of the first sheet, whereby .neither the means of fastening nor thcseams are exposed, substantially as described.

To the above Ihave signed my name this second day ofrMay, 1867.
